Ticks transmit important pathogens affecting cattle such as intracellular bacteria of the genus Anaplasma or protozoa of the order Piroplasmida. This study aimed at assessing tick species present on pastures and cattle and determining occurrence of the tick-borne pathogens Anaplasma phagocytophilum and Babesia spp. in cattle. During May and June 2013, ticks and EDTA blood were collected from 185 dairy cows at six locations in Serbia. Ticks were also collected directly from the pastures at four of these locations...

East Coast fever (ECF) caused by Theileria parva kills cattle in East, Central and Southern Africa leading to significant economic losses. Vaccination is used as a control strategy against ECF and is presently dependent on deliberate infection with live sporozoites and simultaneous treatment with a long-acting oxytetracycline. Although effective, this method has serious limitations; the immunity is parasite strain specific and immunized cattle can become life-long asymptomatic carriers of the parasite, posing risk for the spread of the disease...

Piroplasmid parasites comprising of Babesia , Theileria , and Cytauxzoon are transmitted by ticks to farm and pet animals and have a significant impact on livestock industries and animal health in tropical and subtropical regions worldwide. In addition, diverse Babesia spp. infect humans as opportunistic hosts. Molecular phylogeny has demonstrated at least six piroplasmid lineages exemplified by B. microti , B. duncani , C. felis , T. equi , Theileria sensu stricto ( T. annulata , T. parva , and T. orientalis ) and Babesia sensu stricto ( B...

Malignant ovine theileriosis is a severe tick-borne protozoan disease of sheep and other small ruminants which is widespread in sub-Saharan Africa and the Middle East. The disease is of considerable economic importance in Sudan as the export of livestock provides a major contribution to the gross domestic product of this country. Molecular surveys have demonstrated a high prevalence of sub-clinical infections of Theileria lestoquardi, the causative agent, among small ruminants. No information is currently available on the extent of genetic diversity and genetic exchange among parasites in different areas of the country...

Canine babesiosis is a tick-borne disease caused by several Babesia spp. which have different susceptebility to anti-protozoal drugs. A few drugs and drug combinations are used in the treatment of canine babesiosis often without complete parasite elimination leaving treated dogs as carriers which could relapse with clinical disease and also transmit infection further. Although the large form canine babesial species Babesia canis, Babesia vogeli and Babesia rossi are sensitive to the aromatic diamidines imidocarb dipropionate and diminazene aceturate, small form species such as Babesia gibsoni, Babesia conradae and Babesia vulpes (Theileria annae) are relatively resistant to these drugs and are treated with the combination of the hydroxynaphthoquinone atovaquone and the antibiotic azithromycin...

All Theileria parasites have definitive natural hosts that act as carriers. Incidental infections of uncommon hosts do occur raising questions regarding host specificity and its drivers. Reported hosts for Theileria taurotragi include bushbuck, cattle and eland. More recently T. taurotragi was detected in African buffalo, which may have implications for accurate diagnostics of T. parva. The current study therefore investigated the host specificity of T. taurotragi by developing a specific and sensitive real-time Taqman PCR assay...

Theileriosis is a disease of domesticated animals in tropical and subtropical countries and causes significant reductions in livestock productivity. The arid region of Punjab in Pakistan is notorious for the presence of the vector tick (Acari: Ixodidae) and tick-borne diseases, such as theileriosis and babesiosis. The distribution of Theileria annulata and T. orientalis in the Chakwal district of Punjab was determined by developing a multiplex recombinase polymerase amplification (RPA) assay as a scientific basis for formulating control strategies for bovine theileriosis...

Tick-borne diseases (TBDs), including emerging and re-emerging infectious diseases, are important threats to human and animal health worldwide. Indeed, the number of reported human and animal infectious cases of novel TBD agents has increased in recent decades. However, TBDs tend to be neglected, especially in resource-limited countries that often have limited diagnostic capacity. The aim of this molecular survey was to detect and characterise tick-borne pathogens (Babesia, Theileria, and Hepatozoon parasites and Anaplasmataceae bacteria) in domestic dogs in Zambia...

BACKGROUND: The spherical body is a distinct organelle only existing in Babesia and Theileria. Spherical body proteins (SBPs) are secreted from spherical bodies and incorporated into the cytoplasm of infected erythrocytes during invasion and post-invasion stages. Four different SBP homologues (SBP1, SBP2, SBP3 and SBP4) have been identified in Babesia bovis and Babesia bigemina. So far, there has been no report available about the identification of SBPs in Babesia orientalis. METHODS: The SBP3-like in B...

Theileria annulata is an apicomplexan parasite that infects and transforms bovine macrophages that disseminate throughout the animal causing a leukaemia-like disease called tropical theileriosis. Using deep RNAseq of T. annulata-infected B cells and macrophages we identify a set of microRNAs induced by infection, whose expression diminishes upon loss of the hyper-disseminating phenotype of virulent transformed macrophages. We describe how infection-induced upregulation of miR-126-5p ablates JIP-2 expression to release cytosolic JNK to translocate to the nucleus and trans-activate AP-1-driven transcription of mmp9 to promote tumour dissemination...

Piroplasmosis is caused by several species of protozoa such as the Babesia microti-like piroplasm (Bml), an emerging blood protozoan also known as Theileria annae or Babesia vulpes. Infection by Bml was first reported in dogs in Spain where it is endemic today. Recently, a high prevalence of Bml has been increasingly detected in red foxes (Vulpes vulpes) in European countries. The objective of this study was to determine infection levels of this parasite in foxes from Galicia, NW Spain, and ticks species infestation in these carnivores, where they are so far unknown...

Babesiosis, theileriosis, and anaplasmosis are the most common tick-borne diseases in sheep. The majority of anaplasmosis and theileriosis are subclinical; however, babesiosis causes severe infections in small ruminants. Although there are many reports of co-infections with the agents of these diseases, their clinical severity compared with either of the infections alone is unknown. Within the host, interactions between co-infecting species may cause variations in clinical presentation and response to therapy...
